BLOTTER-BATH.

SPECIFICATION forming part of Letters Patent No. 328,634, dated October 20, 1885.

Application filed June 25, 1885. Serial No. 169,699. (No model) where Figure l is a top view of my improved device with parts cutaway to show construction. Fig. 2 is a front View of the same with parts cut away to show details of construction. Fig. 3 is a view in cross-section of the device on plane denoted by line a: a: of Fig. 2, the changed position of certain parts (the frame) being shown in dotted outline. Fig. 4 is a detail front view of a housing and link. Fig. 5 is a detail end view of the pan.

The object of my invention is to provide a simple and compact device for properly wetting copying-pads; and to this end my invention consists in the combination of the frame, the rollers held in contact with each other by a yielding force, the pan supported on the frame, and in details of the construction and combination of the several parts, as more particularly hereinafter described.

In the accompanying drawings, where like letters indicate the same parts throughout, the letter a denotes the rollerframe as a whole; 6, the standards, of any convenient form and material, in which the frame is pivotally supported on the shaft 0 of the main roller 0, that passes through bearings in the standards. The crank c is fastened to the outer end of the shaft 0 and bears a handle that affords means for rotating it.

The pan (Z is supported between the standards b and below the roller-frame a by means of flanges d on the ends of the pan, that fit and slide in horizontal grooves Z) in the inner faces of the standards; and when the pan is filled with water, and, with the rollers, is in normal position for use, the roller 6 dips more or less into the water.

The roller-frame a is made up of the housings f, through which the shaft 0 passes and turns freely, the top bar, 9, the spring h, at tached to and preferably covered within the top bar, and the links t, that connect the outer ends of spring h with the trunnion or shaft of the lowerroller, e, at both ends of it;

The top bar, 9, extends along the frame over the rolls and rests at each end upon the top of the housings, each of which is perforated for the passage of the shaft 0, and has a link socket, 9, within which the link has a limited lengthwise play.

The spring h is preferably a flat bar of spring metal-as steel-and it is secured to the under side of the top bar at two points, at equal distances from the outer ends of the spring, as by means of the screws h h, and the tension-screw h is seated in a threaded socket in the top bar, near its center, with the point of the screw arranged to thrust against the center of the spring. From the opposite ends of this spring, which overhang the housings, the links 13 are suspended, with their lower ends holding the shaft or trunnion of the lower roll, 6, and by means of the tension-screw h the rollers c and e are held against each other with an adjustable as well as a yielding force, the peculiar arrangement of the single bar-spring and the central tension-screw enabling the pressureto be adjusted at both ends of the rollers from a single point.

In order to place the pan (1 on the standards and below the rollers, the frame a is swung to one side about ninety degrees, turning on the shaft 0 as a pivot-the pintlesj, that slide in sockets in the upper part of the standards, and are held by pins j against dis placement, serving, when thrust into sockets in the housings, as a means for locking the frame both in its vertical and its horizontal position. The pan is preferably semi-cylindrical in outline in cross-section, and is of any convenient materialas tin or iron-the stop (1 serving to limit the movement of the pan in the grooves of the standards, and the partial cover d, with the downturned lip d, preventing the slopping over of water while handling the pan to remove or replace it.

On the top of the back side of the pan is a cover, k, that is attached to its upper edge, near the center, by any convenient means, as the strap is, riveted to both the pan and the cover, with its front edge resting upon the lower roller, 6, above its horizontal center, and pressing down upon orhugging the roller 6 along its edge,either by reason of the weight of the cover or from the spring action of the strap is. The object of this construction and.

arrangement of the cover 70 and roller 6 is to prevent a pad while passing between the rollers from turning down into the pan, and it successfully overcomes a very troublesome difficulty.

lhe front part of the pan, after it has been slid into place, islcovered by a removable lid, Z, that is held in place in grooves in the standards by locking-screws l, whose method of operation is obvious.

In order to moisten a copying-pad with my improved bath, the pad is placed between the rollers, the lower one of which has preferably an elastic covering-as india-rubberand is run between them by turning the roller 0 by means of the handle on the shaft 0'. WVater that adheres to the roller moistens the pad to just the degree determined by the pressure that holds the rollers in contact.

I claim as my invention- 1. In combination, thestandards, the swinging roller-frame pivoted in said standards on the shaft of the main roller, the removable pan supported below the roller-frame, and the cover supported at one edge on the pan, and with its other edge resting on the lower roller, all substantially as described.

2. In combination, the standards, the rollers supported by the standards, the pan into which the lower roller dips, and the cover with its outer edge supported near its center and its inner edge resting on the lowerroller, all sub stantially as described.

3. In combination, the standards, theswinging roller-frame pivoted in said standards on the shaft of the main roller, the removable pan supported below the frame, the rollers, and the locking-pintles movable in sockets in the standards and projecting into sockets in the frame, all substantially as described.

4:. In combination, the standards,the removable pan, the rollers, and the roller-frame with its top bar, the bar-spring attached to the top bar, the housings on the main roller-shaft, the links connecting the outer ends of the spring and the shaft of the lower roller, and the tension-screw arranged to operate against the LEONARD BAILEY.
